cns3xxx: don't use invalid mask value for clock events
...
According to a commit from kernel 4.18-rc3, it's not valid
to use "cpu_mask_all" for clock events and it should be
replaced in favor of "cpu_possible_mask" [1]
This warning was seen when booting kernel 4.19 on a cns3xxx board.
Let's fix it also here just to be safe.

This is triggered by calling eth_schedule_poll(sw) after the IRQ has
been re-enabled.
Rework the network code to only enable IRQ's again if NAPI agrees it's
safe to do so.
Also only re-enable IRQ *after* cleaning up the RX ring and re-enabling
DMA, which otherwise resulted in ugly warnings regarding dirty page
fragments.
These popped up nearly immediately when building the kernel with O2 iso
Os.
--> Note that this change fixes stability issues, at the cost of ~8%
throughput performance.
While at it, also change the iface name being used in warning prints,
making it more obvious: "switch%d" --> "cns3xxx_eth"
The changes have been tested on 4 boards, each moving ~30TB of data
